Two graphics cards on enhanced PCBs, with increased clock speeds and unique cooling systems will not only compete against one another in our today’s test session, but will also stand in a 2-way SLI configuration against a dual-GPU GeForce GTX 690.

The resulting memory bandwidth is as high as 230.4 GB/s, so the Zotac GeForce GTX 770 AMP! Edition should have an edge over the Palit GeForce GTX 770 JetStream:

The ASIC quality of the GPU die is almost the same at 81.0%.

Zotac’s cooler is called Dual Silencer. It consists of an aluminum heatsink with heat pipes, a couple of fans, and a metallic casing.

There are individual aluminum heatsinks with thermal pads on the memory chips and power transistors. The heatsink has five heat pipes, two of which are 8 mm in diameter. The three remaining pipes are 6 mm in diameter.

As opposed to the Palit's cooler, the pipes are soldered to the heatsink, and in a very neat way. The heatsink is cooled by two 70x10mm fans from FirstD:

Their speed is PWM-regulated in a range of 1000 to 3300 RPM. In our temperature test the speed was 2160 RPM when the fans were regulated automatically.

The peak GPU temperature was 81°C. Considering the same GPU clock rates and ASIC quality, the Zotac cooler is not better than the Palit one. It is 3°C worse at the maximum speed of the fans:

Still, the Dual Silencer is quite good at its job.

The Zotac GeForce GTX 770 AMP! Edition doesn’t have high overclocking potential. Its GPU could be overclocked by a mere 35 MHz and its memory, by 580 MHz.
